My question is that which one is more search engine friendly language? CFML
or PHP?
People say that since PHP is more popular than coldfusion so PHP is more SEO
friendly than Coldfusion how far is this correct?. Please ignore other things
like page content ,links etc.
And second question is :-Our company 's most of websites are in coldfusion now
or MD is telling to convert it into PHP because it is free and in terms of
long time sustainance and SEO friendly..
Is this a correct move?...

Re: PHP or Coldfusion?

What Kronin said is a myth. Modern search engines handle messy query strings
fine. Pretty URLs are still nicer for people, though, and certainly easier to
p for a computer, if you want to split hairs. But a query string is not
going to ruin your SEO campaign. If anything, and approach like this will:

"Please ignore other things like page content ,links etc."

In other words:

"Please ignore a couple of the things that matter most in any sensible SEO
effort."

Straight from the horse's mouth (Google, in this case):

Fiction: Sites aren't included in Google's index if they use ASP (or some
other non-html file type.)
Fact:
At Google, we're able to index most types of pages and files with very few
exceptions. A sampling of the file extensions we're able to index includes:
pdf, asp, jsp, html, shtml, xml, doc, xls, ppt, rtf, wks, lwp, wri, swf, cfm,
and php.

If you decide to use dynamic pages (i.e., the URL contains a "?" character),
be aware that not every search engine spider crawls dynamic pages as well as
static pages. It helps to keep the parameters short and the number of them few.

Don't use "&id=" as a parameter in your URLs, as we don't include these pages
in our index.
